Struggling for a concrete lead in the Aarushi murder case, the Central Bureau of Investigation (CBI) has summoned Dr Nupur Talwar for a second lie-detector test. The test is likely to be conducted on Wednesday. <b1>

The test, which was scheduled for Tuesday, was postponed after Nupur did not turn up at the CBI headquarters on time. "The polygraph test would be conducted at the Central Forensic Science Laboratory. Nupur did not come on time as she had gone to visit her husband at Dasna jail," a senior official said. She later arrived at the CBI headquarters with brother-in-law, Dinesh, but left within 10 minutes when she told she was late.

Nupur had earlier been subjected to a polygraph test at the CFSL on June 13. Her psychological assessment was conducted at AIIMS on June 7. CBI said her earlier polygraph test had been "inconclusive". "The 'curves' were 'unreadable' so we were told by experts to take a second polygraph test," the official said. The official added that the murders could be the handiwork of a "professional".

Nupur's daughter Aarushi and servant Hemraj were murdered at their home on the night of May 15-16. Nupur's husband Dr Rajesh Talwar was arrested a week after the murder by the Noida Police.

The CBI hasn't given him a clean chit as yet. The agency has arrested Talwar's compounder, Krishna, in connection with the murders.

They have interrogated dozens of people since they took up the probe but success has eluded them so far. Senior officials said various angles are being probed to ascertain the motive behind the murders. These include differences between family members, the involvement of servants known to Hemraj in the crime and a contract killing angle.

The CBI continued its interrogation of Krishna and another accused in the case, following certain leads. The discrepancies in Krishna's statements to the CBI is giving rise to the suspicion that either he was the person who allegedly carried out the gruesome murders or was actively part of the criminal conspiracy hatched to carry out the killing.
